I don't know how to post a pic on here tbh... it basically the screen that briefly pops up on a normal load before going to windows, where you have to press delete quickly to enter bios.Can you take a pic of the screen?
I assume you tried clear cmos already?
I'd pull any removable USB devices.
I have indeed tried clearing the CMOS. Both by shorting the pins and removing the battery for 10 mins.
I've also tried removing all of the USBs, including the hard drives.
